Windows Setup Hangs on AST Premium 386/386c

ID: Q87362


The information in this article applies to:
  • Microsoft Windows versions 3.0, 3.0a, 3.1, 3.11


SYMPTOMS

When you install Windows 3.0 or 3.1 on an AST premium 386 or 386c computer, the Windows Setup program may stop responding (hang) when switching from MS-DOS mode setup to standard mode setup.


CAUSE

This problem can occur for either of the following reasons:

  • The CMOS settings are enabled for a math coprocessor (80387), but no physical math coprocessor exists.


  • The system contains an older BIOS.



RESOLUTION

Incorrect CMOS Settings

To check or change the AST CMOS settings for a math coprocessor, follow these steps:

  1. Reboot your machine, and press CTRL+ALT+ESC at boot up.


  2. Note or change the math coprocessor setting (Enabled or Disabled). Assume disabled unless it can be verified by physical i*dentification.


  3. Save your changes, and exit from the CMOS setup.


Incorrect BIOS

According to AST technical support, if the BIOS is AST version 2.10 or early or dated earlier than 1988, the BIOS should be updated to AST version 3.01. Contact AST for a BIOS update; the part number for the BIOS is 500- 702-002.
